Abstract

The present invention relates to a compact display apparatus providing similarly sized but much brighter virtual 3D images to a viewer, the apparatus comprising an enclosure; LED illumination based electronic display device; partially transparent and partially reflective viewing surface; and contrast/interference filter screen. The enclosure houses the LED illumination based electronic display device, filter screen and the partially transparent and partially reflective viewing surface. The filter screen is positioned close to the surface of the LED illumination based electronic display device. The LED illumination based electronic display device projects a primary real image onto the filter screen and is optically transmitted onto the partially transparent and partially reflective viewing surface. The partially transparent and partially reflective viewing surface reflects a secondary virtual 3D image perceivable on the opposite side of the partially transparent and partially reflective viewing surface to the LED illumination based electronic display device.
